Horizontal Directional Drilling (HDD) work to commence:
From 13 July, the project will begin Horizontal Directional Drilling (HDD) works at the Landfall site. HDD is a trenchless construction method that enables underground ducts to be installed with minimal surface disturbance.
For this project, HDD will be used to create a connection between the onshore cable route and the offshore infrastructure, allowing the future installation of cables beneath the shoreline without the need for extensive excavation across the beach and coastal area. Due to the continuous nature of the drilling process, works will operate 24 hours a day, seven days a week for approximately six months. Construction crews will work split shifts between 7am and 7pm, while Access Point 1 (AP1) will remain operational 24/7.
We will continue to take steps to minimise disruption to local residents and keep the community informed as works progress.
Cable route and Landfall Construction update - East Anglia TWO and East Anglia ONE North
In April, ScottishPower Renewables (SPR) hosted a drop-in information day at Thorpeness Country Club to discuss ongoing and upcoming works on the East Anglia TWO and East Anglia ONE North onshore cable route. This included providing information on the Horizontal Directional Drill (HDD) works at landfall to the north of Thorpeness. These works are now due to commence in the coming weeks.
Recent and ongoing works include constructing the haul road to the landfall construction consolidation site (CCS), constructing the landfall CCS, and taking delivery of the drill rigs and other associated plant. This has enabled mobilisation of landfall works.
Abnormal loads
An abnormal load (AIL) is scheduled for Monday 22nd June. This will be under a police escort. The route these loads follow is subject to the police escort and therefore may not always travel down approved routes. They are carefully planned and scheduled with consideration to other AILs and works in the area.
Horizontal Directional Drill (HDD) update
With the Landfall Works commencing, you may notice an increase in activity at and around the Landfall CCS. The Landfall Works will begin with installation of the rig anchors plus casing to support the first section of the HDDs. These works will be done under normal working hours. These are:
- Monday to Friday: 8:00am – 6:00pm
- Saturday: 8:00am – 1:00pm
The HDD rigs can then commence the pilot hole drill from onshore to offshore, anticipated to commence the week beginning 22nd June. At this point, the works necessitate twenty-four-hour working to maintain bore stability. There are four HDDs required in total, with each expected to take six to eight weeks approximately to complete. There will be a pause in twenty-four-hour works between each HDD for supplementary works that do not require such working hours.
As shown at our public information drop-in event, there will be a jack-up barge deployed approximately 1.6km offshore to support the HDD works. The jack-up barge and support vessels may be visible from the shoreline. A Notice to Mariners has been posted separately.
If you missed our information day in April, all the materials shown have been uploaded to the East Anglia TWO document library, linked below. These include maps and diagrams of the landfall site, approved traffic routes, and more about the wider project.

East Anglia THREE – Donation towards Martlesham Wilds (27 April 2026)
ScottishPower Renewables has announced a £35,000 donation towards one of Suffolk’s newest nature reserves.
The donation – which will go towards the costs for the Martlesham Wilds Nature Reserve’s site manager over the next two years – was confirmed as colleagues from ScottishPower Renewables’ East Anglia THREE offshore windfarm paid a visit to the Suffolk Wildlife Trust site near Ipswich.
Situated on the banks of the River Deben and covering 289 acres, Suffolk Wildlife Trust began to return Martlesham Wilds to nature in 2023. More information is available here.
East Anglia THREE - Record set for biggest offshore blade install (21 April 2026)
SPR and Masdar’s East Anglia THREE offshore windfarm has set a UK offshore wind record with the installation of its first turbine – the first in the UK to feature 115 metre blades, each one longer than a Premier League football pitch.
All 285 of the record-breaking blades for the project’s 95 turbines are being manufactured in the UK at Siemens Gamesa’s factory in Hull.
Standing around 262 metres tall – higher than the observation deck at the Shard – the 14MW Siemens Gamesa turbines have a rotor diameter of 236 metres.
A single revolution of just one turbine will produce enough electricity to power a UK home for more than four days, charge around 1,700 mobile phones, or brew nearly a thousand cups of tea.

East Anglia THREE community engagement
Edward Rees re-joined ScottishPower Renewables last year as Community Liaison Officer for East Anglia THREE, having previously worked on East Anglia ONE. Edward organised Public Information Days prior to the installation of temporary Consolidated Construction Sites (CCSs) last summer, giving the local community an opportunity to meet the project management team and ask questions about the construction works.
Further events will be held in summer 2023, prior to the installation of the remaining CCSs. Organisations can also request SPR attendance at events and meetings and, dependent on programme and availability, these will be honoured where possible.
If you have any questions about East Anglia THREE, you can contact us at eastangliathree@scottishpower.com. Further information on our approach to community engagement is available in our Project Community and Public Relations Procedure.
